How can you tell the difference between cast iron and malleable iron?
Malleable iron is relatively easy to machine, and it is shock resistant. Cast iron contains about two percent carbon, which makes it stronger and more resistant to rusting. But this also makes it more difficult to machine because it is difficult to get a smooth surface with the material.

Although not cast as easily as gray iron or ductile iron, it will cast better than some other materials, including white iron. Additionally, malleable iron offers excellent surface hardening.
Are black pipe fittings weldable?
Black iron pipe is simply mild low carbon steel so it can be welded to most grades of steel.
